I happen to be a particular fan of unisex watches, and NOMOS Glashütte timepieces are particular favorites of mine. Many of its watches are sized for a male or female wrist, and they feature minimalist case and dial designs with a healthy dose of Bauhaus. Even the names of many of its collections, like Metro, Tetra and Autobahn—give little away as to their intended audience.

Now, just in time for summer, two new Aqua watches are being introduced . The Aqua series, as its name suggests, is designed for beach lovers, with sturdy steel cases and see-through casebacks that are “extra-water resistant” to 200 meters, according to the Germany-based brand. Available in the Ahoi and Club collections in July, the watches sport a red, white and blue palette that is both nautical and, of course, a Fourth of July favorite.

These watches each have a “siren white” dial, with blue hands and red hour markers and a red small seconds hand. Arabic numerals are at 12, 2, 4, 8 and 10, and on the seconds subdial, blue Arabic numerals are at 20, 40 and 60. Superluminova detailing on the dial makes the watches practical and attractive from sunup til sundown.

Both watches feature the NOMOS automatic caliber DUW 3001 (introduced in 2015) whose pace-setting component is the NOMOS swing system, which is the company’s proprietary escapement introduced in 2014. The 27-jewel DUW3001, the company’s tenth in-house caliber, is only 3.2 millimeters in height, and requires just a few motions of the arm to wind it fully. Its balance bridge is fixed by screws on both sides, and the movement is decorated with rhodium-plated surfaces with Glashütte ribbing and NOMOS perlage. It has a bi-directional winding rotor and Glashütte three-quarter plate.

The Ahoi neomatik siren white is 36mm in diameter, while its height is 9.55mm, owed in part to the movement thickness. The watch’s waterproof textile strap is in light gray with decorative topstitching, and the lug width is 18mm. The Club neomatik siren white is 37mm in diameter, and its height is 9.27mm. It, too, has a woven, waterproof strap in light gray.

These new watches in the Aqua series join others in the Ahoi and Club collections. In the Ahoi, there is a 40mm model and a 36mm model, and each includes an incredible siren blue dial, in addition to white and navy. The siren blue color is a beachy blue, that looks just like the waters off the coast of Bermuda, if memory serves me correctly. The 36mm Ahoi also includes a siren red version, which reminds me of a spectacular sunset. In the Club collection, there are 41mm models as well as 36mm models, and like the Ahoi, some of the larger models include a date window at 6 o’clock. Also like the Ahoi, they come in a variety of dial colors, including siren blue and siren red. All have small seconds subdials.
